+
+      <description>
+		<para>When a barrier is created, it is initialized with a thread count N.
+		The first N-1 calls to <code>wait()</code> will all cause their threads to be blocked. 
+		The Nth call to <code>wait()</code> will allow all  of the waiting threads, including 
+		the Nth thread, to be placed in a ready state.  The Nth call will also "reset"
+		the barrier such that, if an additional N+1th call is made to <code>wait()</code>, 
+		it will be as though this were the first call to <code>wait()</code>; in other
+		words, the N+1th to 2N-1th calls to <code>wait()</code> will cause their
+		threads to be blocked, and the 2Nth call to <code>wait()</code> will allow all of 
+		the waiting threads, including the 2Nth thread, to be placed in a ready state
+		and reset the barrier. This functionality allows the same set of N threads to re-use 
+		a barrier object to  synchronize their execution at multiple points during their 
+		execution.</para>

+	How you build the &Boost.Threads; libraries, and how you build your own applications
+	that use those libraries, are some of the most frequently asked questions. Build
+	processes are difficult to deal with in a portable manner. That's one reason
+	why &Boost.Threads; makes use of &Boost.Build;.
+	In general you should refer to the documentation for &Boost.Build;.
+	This document will only supply you with some simple usage examples for how to
+	use <emphasis>bjam</emphasis> to build and test &Boost.Threads;. In addition, this document
+	will try to explain the build requirements so that users may create their own
+	build processes (for instance, create an IDE specific project), both for building
+	and testing &Boost.Threads;, as well as for building their own projects using
+	&Boost.Threads;.

+	To build the &Boost.Threads; libraries using &Boost.Build;, simply change to the
+	directory <emphasis>boost_root</emphasis>/libs/thread/build and execute the command:
+		<programlisting>bjam -sTOOLS=<emphasis>toolset</emphasis></programlisting>
+	This will create the debug and the release builds of the &Boost.Threads; library.
+	<note>Invoking the above command in <emphasis>boost_root</emphasis> will build all of 
+	the Boost distribution, including &Boost.Threads;.</note>
+		</para>
+		<para>
+	The Jamfile supplied with &Boost.Threads; produces a dynamic link library named
+	<emphasis>boost_thread{build-specific-tags}.{extension}</emphasis>, where the build-specific
+	tags indicate the toolset used to build the library, whether it's a debug or release
+	build, what version of Boost was used, etc.; and the extension is the appropriate extension
+	for a dynamic link library for the platform for which &Boost.Threads; is being built.
+	For instance, a debug library built for Win32 with VC++ 7.1 using Boost 1.31 would
+	be named <emphasis>boost_thread-vc71-mt-gd-1_31.dll</emphasis>.
+		</para>
+		<para>
+	The source files that are used to create the &Boost.Threads; library
+	are all of the *.cpp files found in <emphasis>boost_root</emphasis>/libs/thread/src.
+	These need to be built with the compiler's and linker's multi-threading support enabled.
+	If you want to create your own build solution you'll have to follow these same
+	guidelines. One of the most frequently reported problems when trying to do this
+	occurs from not enabling the compiler's and linker's support for multi-threading.

+      </purpose>
+
+      <description>
+        <para>A <classname>condition</classname> object is always used in
+          conjunction with a <link linkend="threads.concepts.mutexes">mutex</link>
+          object (an object whose type is a model of a <link
+            linkend="threads.concepts.Mutex">Mutex</link> or one of its
+          refinements). The mutex object must be locked prior to waiting on the
+          condition, which is verified by passing a lock object (an object whose
+          type is a model of <link linkend="threads.concepts.Lock">Lock</link> or
+          one of its refinements) to the <classname>condition</classname> object's
+          wait functions. Upon blocking on the <classname>condition</classname>
+          object, the thread unlocks the mutex object. When the thread returns
+          from a call to one of the <classname>condition</classname> object's wait
+          functions the mutex object is again locked. The tricky unlock/lock
+          sequence is performed automatically by the
+          <classname>condition</classname> object's wait functions.</para>
+        <para>The <classname>condition</classname> type is often used to
+          implement the Monitor Object and other important patterns (see
+          &cite.SchmidtStalRohnertBuschmann; and &cite.Hoare74;). Monitors are one

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>An object of class <code>condition</code> is a synchronization
-        primitive used to cause a thread to wait until a particular shared-data
-        condition (or time) is met. A <code>condition</code> object is always
-        used in conjunction with a mutex object modeling a <a href=
-        "mutex_concept.html">Mutex Concept</a>. The mutex must be locked prior
-        to waiting on the <code>condition</code>, which is ensured by passing a
-        lock object modeling a <a href="lock_concept.html">Lock Concept</a> to
-        the <code>condition</code> object&#39;s <code>wait</code> functions.
-        While the thread is waiting on the <code>condition</code> object, the
-        mutex associated with the lock is unlocked. When the thread returns
-        from a call to one of the <code>condition</code> object&#39;s <code>
-        wait</code> functions, the mutex is again locked. The tricky
-        lock/unlock/lock sequence is performed automatically by the <code>
-        condition</code> object&#39;s <code>wait</code> functions.</p>
-
-        <p>The <code>condition</code> type is often used to implement the <i>
-        Monitor Object</i> and other important patterns. See <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a> and <a href=
-        "bibliography.html#Hoare-74">[Hoare 74]</a>. Monitors are one of the
-        most important patterns for creating reliable multithreaded
-        programs.</p>
-
-        <p>See <a href="definitions.html">Formal Definitions</a> for
-        definitions of thread states <a href="definitions.html#state">
-        blocked</a> and <a href="definitions.html#state">ready</a>. Note that
-        &quot;waiting&quot; is a synonym for blocked.</p>

-
-        <h2>Introduction</h2>
-
-        <p>The definitions are given in terms of the <a href=
-        "bibliography.html#ISO-98">C++ Standard</a>. References to the standard
-        are in the form [1.2.3/4], which represents the section number, with
-        the paragraph number following the &quot;/&quot;.</p>
-
-        <p>Because the definitions are written in something akin to
-        &quot;standardese&quot;, they can be difficult to understand. The
-        intent isn&#39;t to confuse, but rather to clarify the additional
-        requirements Boost.Threads places on a C++ implementation as defined by
-        the C++ Standard.</p>
-
-        <h2>Definitions</h2>
-
-        <h3>Thread</h3>
-
-        <p>Thread is short for &quot;thread of execution&quot;. A thread of
-        execution is an execution environment [1.9/7] within the execution
-        environment of a C++ program [1.9]. The main() function [3.6.1] of the
-        program is the initial function of the initial thread. A program in a
-        multi-threading environment always has an initial thread even if the
-        program explicitly creates no additional threads.</p>
-
-        <p>Unless otherwise specified, each thread shares all aspects of its
-        execution environment with other threads in the program. Shared aspects
-        of the execution environment include, but are not limited to, the
-        following:</p>
-
-        <ul>
-            <li>Static storage duration (static, extern) objects [3.7.1].</li>
-        </ul>
-
-        <ul>
-            <li>Dynamic storage duration (heap) objects [3.7.3]. Thus each
-            memory allocation will return a unique addresses, regardless of the
-            thread making the allocation request.</li>
-        </ul>
-
-        <ul>
-            <li>Automatic storage duration (stack) objects [3.7.2] accessed via
-            pointer or reference from another thread.</li>
-        </ul>
-
-        <ul>
-            <li>Resources provided by the operating system. For example,
-            files.</li>
-        </ul>
-
-        <ul>
-            <li>The program itself. In other words, each thread is executing
-            some function of the same program, not a totally different
-            program.</li>
-        </ul>
-
-        <p>Each thread has its own:</p>
-
-        <ul>
-            <li>Registers and current execution sequence (program counter)
-            [1.9/5].</li>
-        </ul>
-
-        <ul>
-            <li>Automatic storage duration (stack) objects [3.7.2].</li>
-        </ul>
-
-        <h3><a name="Thread-safe">Thread-safe</a></h3>
-
-        <p>A program is thread-safe if it has no <a href="#Race condition">race
-        conditions</a>, does not <a href="#Deadlock">deadlock</a>, and has no
-        <a href="#Priority failure">priority failures</a>.</p>
-
-        <p>Note that thread-safety does not necessarily imply efficiency, and
-        than while some thread-safety violations can be determined statically
-        at compile time, many thread-safety errors can only only be detected at
-        runtime.</p>
-
-        <h3>Thread <a name="State">State</a></h3>
-
-        <p>During the lifetime of a thread, it shall be in one of the following
-        states:</p>

-
-        <p>[Note: if a suspend() function is added to the threading library,
-        additional transitions to the blocked state will have to be added to
-        the above table.]</p>
-
-        <h3><a name="Race condition">Race condition</a></h3>
-
-        <p>A race condition is what occurs when multiple threads read and write
-        to the same memory without proper synchronization, resulting in an
-        incorrect value being read or written. The result of a race condition
-        may be a bit pattern which isn&#39;t even a valid value for the data
-        type. A race condition results in undefined behavior [1.3.12].</p>
-
-        <p>Race conditions can be prevented by serializing memory access using
-        the tools provided by Boost.Threads.</p>
-
-        <h3><a name="Deadlock">Deadlock</a></h3>
-
-        <p>Deadlock is an execution state where for some set of threads, each
-        thread in the set is blocked waiting for some action by one of the
-        other threads in the set. Since each is waiting on the others, none
-        will ever become ready again.</p>
-
-        <h3><a name="Priority failure">Priority failure</a></h3>
-
-        <p>A priority failure (such as priority inversion or infinite
-        overtaking) occurs when threads executed in such a sequence that
-        required work is not performed in time to be useful.</p>
-
-        <h2>Memory visibility between threads</h2>
-
-        <p>An address [1.7] shall always point to the same memory byte,
-        regardless of the thread or processor dereferencing the address.</p>
-
-        <p>An object [1.8, 1.9] is accessible from multiple threads if it is of
-        static storage duration (static, extern) [3.7.1], or if a pointer or
-        reference to it is explicitly or implicitly dereferenced in multiple
-        threads.</p>
-
-        <p>For an object accessible from multiple threads, the value of the
-        object accessed from one thread may be indeterminate or different than
-        the value accessed from another thread, except under the conditions
-        specified in the following table. For the same row of the table, the
-        value of an object accessible at the indicated sequence point in thread
-        A will be determinate and the same if accessed at or after the
-        indicated sequence point in thread B, provided the object is not
-        otherwise modified. In the table, the &quot;sequence point at a
-        call&quot; is the sequence point after the evaluation of all function
-        arguments [1.9/17], while the &quot;sequence point after a call&quot;
-        is the sequence point after the copying of the returned value...&quot;
-        [1.9/17].</p>

+  <title>Design</title>
+  <para>With client/server and three-tier architectures becoming common place
+  in today's world, it's becoming increasingly important for programs to be
+  able to handle parallel processing. Modern day operating systems usually
+  provide some support for this through native thread APIs. Unfortunately,
+  writing portable code that makes use of parallel processing in C++ is made
+  very difficult by a lack of a standard interface for these native APIs.
+  Further, these APIs are almost universally C APIs and fail to take
+  advantage of C++'s strengths, or to address concepts unique to C++, such as
+  exceptions.</para>
+  <para>The &Boost.Threads; library is an attempt to define a portable interface
+  for writing parallel processes in C++.</para>
+  <section id="threads.design.goals">
+    <title>Goals</title>
+    <para>The &Boost.Threads; library has several goals that should help to set
+	it apart from other solutions. These goals are listed in order of precedence
+	with full descriptions below.
+    <variablelist>
+	  <varlistentry>
+	    <term>Portability</term>
+		<listitem>
+          <para>&Boost.Threads; was designed to be highly portable. The goal is
+		  for the interface to be easily implemented on any platform that
+		  supports threads, and possibly even on platforms without native thread
+		  support.</para>

+	  <varlistentry>
+        <term>Safety</term>
+        <listitem>

+		  <link linkend="threads.glossary.thread-safe">thread-safe</link>
+		  code is very difficult and successful libraries must strive to
+		  insulate the programmer from dangerous constructs as much as
+		  possible. This is accomplished in several ways:
+          <itemizedlist>
+            <listitem>
+              <para>C++ language features are used to make correct usage easy
+			  (if possible) and error-prone usage impossible or at least more
+			  difficult. For example, see the <link

+			  linkend="threads.concepts.Lock">Lock</link> designs, and note
+			  how they interact.</para>
+            </listitem>

+              identified as such in the documentation to make users aware of

+	  </varlistentry>

+	    <term>Flexibility</term>
+		<listitem>
+		  <para>&Boost.Threads; was designed to be flexible. This goal is often
+		  at odds with <emphasis>safety</emphasis>. When functionality might be
+		  compromised by the desire to keep the interface safe, &Boost.Threads;
+		  has been designed to provide the functionality, but to make it's use
+		  prohibitive for general use. In other words, the interfaces have been
+		  designed such that it's usually obvious when something is unsafe, and
+		  the documentation is written to explain why.</para>
+        </listitem>
+	  </varlistentry>
+      <varlistentry>
+        <term>Efficiency</term>
+		<listitem>
+          <para>&Boost.Threads; was designed to be as efficient as
+		  possible. When building a library on top of another library there is
+		  always a danger that the result will be so much slower than the
+		  "native" API that programmers are inclined to ignore the higher level
+		  API. &Boost.Threads; was designed to minimize the chances of this
+		  occurring. The interfaces have been crafted to allow an implementation
+		  the greatest chance of being as efficient as possible. This goal is
+		  often at odds with the goal for <emphasis>safety</emphasis>. Every
+		  effort was made to ensure efficient implementations, but when in
+		  conflict <emphasis>safety</emphasis> has always taken

+    <title>Iterative Phases</title>
+    <para>Another goal of &Boost.Threads; was to take a dynamic, iterative
+	approach in its development. The computing industry is still exploring the
+	concepts of parallel programming. Most thread libraries supply only simple
+	primitive concepts for thread synchronization. These concepts are very
+	simple, but it is very difficult to use them safely or to provide formal
+	proofs for constructs built on top of them. There has been a lot of research
+	into other concepts, such as in "Communicating Sequential Processes."
+	&Boost.Threads; was designed in iterative steps, with each step providing 
+	the building blocks necessary for the next step and giving the researcher 
+	the tools necessary to explore new concepts in a portable manner.</para>
+    <para>Given the goal of following a dynamic, iterative approach
+	&Boost.Threads; shall go through several growth cycles. Each phase in its
+	development shall be roughly documented here.</para>

+  <section>
+    <title>Phase 1, Synchronization Primitives</title>
+    <para>Boost is all about providing high quality libraries with
+	implementations for many platforms. Unfortunately, there's a big problem
+	faced by developers wishing to supply such high quality libraries, namely
+	thread-safety. The C++ standard doesn't address threads at all, but real
+	world programs often make use of native threading support. A portable
+	library that doesn't address the issue of thread-safety is therefore not
+	much help to a programmer who wants to use the library in his multithreaded
+	application. So there's a very great need for portable primitives that will
+	allow the library developer to create <link
+	linkend="threads.glossary.thread-safe">thread-safe</link>
+	implementations. This need far out weighs the need for portable methods to
+	create and manage threads.</para>
+    <para>Because of this need, the first phase of &Boost.Threads; focuses
+	solely on providing portable primitive concepts for thread
+	synchronization. Types provided in this phase include the
+	<classname>boost::mutex</classname>, 
+	<classname>boost::try_mutex</classname>,
+	<classname>boost::timed_mutex</classname>, 
+	<classname>boost::recursive_mutex</classname>,
+	<classname>boost::recursive_try_mutex</classname>,
+	<classname>boost::recursive_timed_mutex</classname>, and
+	<classname>boost::lock_error</classname>. These are considered the "core"
+	synchronization primitives, though there are others that will be added in
+	later phases.</para>
+  </section>
+  <section id="threads.design.phase2">
+    <title>Phase 2, Thread Management and Thread Specific Storage</title>
+    <para>This phase addresses the creation and management of threads and
+    provides a mechanism for thread specific storage (data associated with a
+    thread instance). Thread management is a tricky issue in C++, so this
+    phase addresses only the basic needs of multithreaded program. Later
+    phases are likely to add additional functionality in this area. This
+    phase of &Boost.Threads; adds the <classname>boost::thread</classname> and
+	<classname>boost::thread_specific_ptr</classname> types. With these
+	additions the &Boost.Threads; library can be considered minimal but
+	complete.</para>
+  </section>
+  <section>
+    <title>The Next Phase</title>
+    <para>The next phase will address more advanced synchronization concepts,
+    such as read/write mutexes and barriers.</para>

-        <h2>1. Are lock objects <a href="definitions.html#Thread-safe">
-        thread-safe</a>?</h2>
-
-        <p><b>No!</b> Lock objects are not meant to be shared between threads.
-        They are meant to be short lived objects created on automatic storage
-        within a code block. Any other usage is just likely to lead to errors
-        and won&#39;t really be of actual benefit any way. Share <a href=
-        "mutex_concept.html">mutexes</a>, not locks. For more information see
-        the <a href="rationale.html#lock_objects">rationale</a> behind the
-        design for lock objects.</p>
-
-        <h2>2a. Why was Boost.Threads modeled after (specific library
-        name)?</h2>
-
-        <p>It wasn&#39;t. Boost.Threads was designed from scratch. Extensive
-        design discussions involved numerous people representing a wide range
-        of experience across many platforms. To ensure portability, the initial
-        implements were done in parallel using POSIX Threads and theWin32
-        threading API. But the Boost.Threads design is very much in the spirit
-        of C++, and thus doesn&#39;t model such C based APIs.</p>
-
-        <h2>2b. Why wasn&#39;t Boost.Threads modeled after (specific library
-        name)?</h2>
-
-        <p>Existing C++ libraries either seemed dangerous (often failing to
-        take advantage of prior art to reduce errors) or had excessive
-        dependencies on library components unrelated to threading. Existing C
-        libraries couldn&#39;t meet our C++ requirements, and were also missing
-        certain features. For instance, the WIN32 thread API lacks condition
-        variables, even though these are critical for the important Monitor
-        pattern <a href="bibliography.html#Schmidt-00">[Schmidt 00]</a>.</p>
-
-        <h2>3. Why do <a href="mutex_concept.html">Mutexes</a> have noncopyable
-        semantics?</h2>
-
-        <p>To ensure that <a href="definitions.html#Deadlock">deadlocks</a>
-        don&#39;t occur. The only logical form of copy would be to use some
-        sort of shallow copy semantics in which multiple mutex objects could
-        refer to the same mutex state. This means that if ObjA has a mutex
-        object as part of its state and ObjB is copy constructed from it, then
-        when ObjB::foo() locks the mutex it has effectively locked ObjA as
-        well. This behavior can result in deadlock. Other copy semantics result
-        in similar problems (if you think you can prove this to be wrong then
-        supply us with an alternative and we&#39;ll reconsider).</p>
-
-        <h2>4. How can you prevent <a href="definitions.html#Deadlock">
-        deadlock</a> from occurring when a thread must lock multiple
-        mutexes?</h2>
-
-        <p>Always lock them in the same order. One easy way of doing this is to
-        use each mutex&#39;s address to determine the order in which they are
-        locked. A future Boost.Threads concept may wrap this pattern up in a
-        reusable class.</p>
-
-        <h2>5. Don&#39;t noncopyable <a href="mutex_concept.html">mutex</a>
-        semantics mean that a class with a mutex member will be noncopyable as
-        well?</h2>
-
-        <p>No, but what it does mean is that the compiler can&#39;t generate a
-        copy constructor and assignment operator, so they will have to be coded
-        explicitly. This is a <b>good thing</b>, however, since the compiler
-        generated operations would not be <a href=
-        "definitions.html#Thread-safe">thread-safe</a>. The following is a
-        simple example of a class with copyable semantics and internal
-        synchronization through a mutex member.</p>
-<pre>
-class counter
-{
-public:
-   // Doesn't need synchronization since there can be no references to *this
-   // until after it's constructed!
-   explicit counter(int initial_value)
-      : m_value(initial_value)
-   {
-   }
-   
-   // We only need to syncronize other for the same reason we don't have to
-   // synchronize on construction!
-   counter(const counter&amp; other)
-   {
-      boost::mutex::scoped_lock scoped_lock(other.m_mutex);
-      m_value = other.m_value;
-   }
-   
-   // For assignment we need to synchronize both objects!
-   const counter&amp; operator=(const counter&amp; other)
-   {
-      if (this == &amp;other)
-         return *this;
-         
-      boost::mutex::scoped_lock lock1(&amp;m_mutex &lt; &amp;other.m_mutex ? m_mutex : other.m_mutex);
-      boost::mutex::scoped_lock lock2(&amp;m_mutex &gt; &amp;other.m_mutex ? m_mutex : other.m_mutex);
-      m_value = other.m_value;
-      
-      return *this;
-   }
-   
-   int value() const
-   {
-      boost::mutex::scoped_lock scoped_lock(m_mutex);
-      return m_value;
-   }
-   int increment()
-   {
-      boost::mutex::scoped_lock scoped_lock(m_mutex);
-      return ++m_value;
-   }
-   
-private:
-   mutable boost::mutex m_mutex;
-   int m_value;
-};
-</pre>
-
-        <h2>6. How can you lock a <a href="mutex_concept.html">mutex</a> member
-        in a const member function, in order to implement the Monitor
-        Pattern?</h2>
-
-        <p>The Monitor Pattern mutex <a href="bibliography.html#Schmidt-00">
-        [Schmidt 00]</a> should simply be declared as mutable. See the example
-        code above. The internal state of mutex types could have been made
-        mutable, with all lock calls made via const functions, but this does a
-        poor job of documenting the actual semantics. Declaring a mutex member
-        as mutable clearly documentations the intended semantics.</p>
-
-        <h2>7. Why supply <a href="condition.html">condition variables</a>
-        rather than <a href="rationale.html#Events">event variables</a>?</h2>
-
-        <p>Condition variables result in user code much less prone to <a href=
-        "definitions.html#Race condition">race conditions</a> than event
-        variables. See <a href="rationale.html#Events">Rationale</a> for
-        analysis. Also see <a href="bibliography.html#Hoare-74">[Hoare74]</a>
-        and <a href="bibliography.html#Schmidt-00">[Schmidt 00]</a>.</p>
-
-        <h2>8. Why isn&#39;t thread cancellation or termination provided?</h2>
-
-        <p>There&#39;s a valid need for thread termination, so at some point
-        Boost.Threads probably will include it, but only after we can find a
-        truly safe (and portable) mechanism for this concept.</p>
-
-        <h2>9. Is it safe for threads to share automatic storage duration
-        (stack) objects via pointers or references?</h2>
-
-        <p>Only if you can guarantee that the lifetime of the stack object will
-        not end while other threads might still access the object. Thus the
-        safest practice is to avoid sharing stack objects, particularly in
-        designs where threads are created and destroyed dynamically. Restrict
-        sharing of stack objects to simple designs with very clear and
-        unchanging function and thread lifetimes. (Suggested by Darryl
-        Green).</p>
-
-        <h2>10. Why has class semaphore disappeared?</h2>
-
-        <p>Semaphore was removed as too error prone. The same effect can be
-        achieved with greater safety by the combination of a mutex and a
-        condition variable.</p>

+			In the current Win32 implementation, creating a boost::thread object
+			during dll initialization will result in deadlock because the thread 
+			class constructor causes the current thread to wait on the thread that 
+			is being created until it signals that it has finished its initialization,

-        <h3>Motivation</h3>
-
-        <p>With client/server and three-tier architectures becoming common
-        place in today&#39;s world, it&#39;s becoming increasingly important
-        for programs to be able to handle parallel processing. Modern day
-        operating systems usually provide some support for this through native
-        thread APIs. Unfortunately, writing portable code that makes use of
-        parallel processing in C++ is made very difficult by a lack of a
-        standard interface for these native APIs. Further, these APIs are
-        almost universally C APIs and fail to take advantage of C++&#39;s
-        strengths, or to address C++&#39;s issues.</p>
-
-        <p>The <b>Boost.Threads</b> library is an attempt to define a portable
-        interface for writing parallel processes in C++.</p>
-
-        <h3>Goals</h3>
-
-        <p>The <b>Boost.Threads</b> library has several goals that should help
-        to set it apart from other solutions. These goals are listed in order
-        of precedence with full descriptions below.</p>
-
-        <ul>
-            <li>
-                <b>Portability</b> 
-
-                <p><b>Boost.Threads</b> was designed to be highly portable. The
-                goal is for the interface to be easily implemented on any
-                platform that supports threads, and possibly even on platforms
-                without native thread support.</p>
-            </li>
-
-            <li>
-                <b>Safety</b> 
-
-                <p><b>Boost.Threads</b> was designed to be as safe as possible.
-                Writing <a href="definitions.html#Thread-safe">thread-safe</a>
-                code is very difficult and successful libraries must strive to
-                insulate the programmer from dangerous constructs as much as
-                possible. This is accomplished in several ways:</p>
-
-                <ul>
-                    <li>
-                        <p align="left">C++ language features are used make
-                        correct usage easy (if possible, the default) and
-                        error-prone impossible or at least more difficult. For
-                        example, see the <a href="mutex_concept.html">Mutex</a>
-                        and <a href="lock_concept.html">Lock</a> designs, and
-                        how note how they interact.</p>
-                    </li>
-
-                    <li>
-                        <p align="left">Certain traditional concurrent
-                        programming features are considered so error-prone that
-                        they are not provided at all. For example, see the <a
-                        href="rationale.html#Events">Events Not Provided</a>
-                        rationale.</p>
-                    </li>
-
-                    <li>
-                        <p align="left">Dangerous features, or features which
-                        may be misused, are identified as such in the
-                        documentation to make users aware of potential
-                        pitfalls.</p>
-                    </li>
-                </ul>
-            </li>
-
-            <li>
-                <b>Flexibility</b> 
-
-                <p><b>Boost.Threads</b> was designed to be flexible. This goal
-                is often at odds with <i>safety</i>. When functionality might
-                be compromised by the desire to keep the interface safe, <b>
-                Boost.Threads</b> has been designed to provide the
-                functionality, but to make it&#39;s use prohibitive for general
-                use.</p>
-            </li>
-
-            <li>
-                <b>Efficiency</b> 
-
-                <p><b>Boost.Threads</b> was designed to be as efficient as
-                possible. When building a library on top of another library
-                there is always a danger that the result will be so much slower
-                than the &quot;native&quot; API that programmers are inclined
-                to ignore the higher level API. <b>Boost.Threads</b> was
-                designed to minimize the chances of this occurring. The
-                interfaces have been crafted to allow an implementation the
-                greatest chance of being as efficient as possible. This goal is
-                often at odds with the goal for <i>safety</i>. Every effort was
-                made to ensure efficient implementations, but when in conflict
-                <i>safety</i> has always taken precedence.</p>
-            </li>
-        </ul>
-
-        <h3>Iterative Phases</h3>
-
-        <p>Another goal of <b>Boost.Threads</b> was to take a dynamic,
-        iterative approach in its development. The computing industry is still
-        exploring the concepts of parallel programming. Most thread libraries
-        supply only simple primitive concepts for thread synchronization. These
-        concepts are very simple, but they are very difficult to use safely or
-        to provide formal proofs for constructs built on top of them. Until
-        recently, these primitives were &quot;state of the art&quot; and the
-        only concepts available to programmers. Recently there has been a lot
-        of research in other concepts, such as in &quot;Communicating
-        Sequential Processes.&quot; <b>Boost.Threads</b> was designed in
-        iterative steps, providing the building blocks necessary for the next
-        step, and giving the researcher the tools necessary to explore new
-        concepts in a portable manner.</p>
-
-        <p>Given the goal of following a dynamic, iterative approach <b>
-        Boost.Threads</b> shall go through several growth cycles. Each phase in
-        its development shall be roughly documented here.</p>
-
-        <h4>Phase 1, Synchronization Primitives</h4>
-
-        <p>Boost is all about providing high quality libraries with
-        implementations for many platforms. Unfortunately, there&#39;s a big
-        problem faced by developers wishing to supply such high quality
-        libraries, namely thread-safety. The C++ standard doesn&#39;t address
-        threads at all, but real world programs often make use of native
-        threading support. A portable library that doesn&#39;t address the
-        issue of thread-safety is there for not much help to a programmer who
-        wants to use the library in his multi-threaded application. So
-        there&#39;s a very great need for portable primitives that will allow
-        the library developer to create <a href="definitions.html#Thread-safe">
-        thread-safe</a> implementations. This need far out weighs the need for
-        portable methods to create and manage threads.</p>
-
-        <p>Because of this need, the first phase of <b>Boost.Threads</b>
-        focuses solely on providing portable primitive concepts for thread
-        synchronization. Types provided in this phase include the <a href="mutex.html">
-        mutex/try_mutex/timed_mutex</a>, <a href="recursive_mutex.html">
-        recursive_mutex/recursive_try_mutex/recursive_timed_mutex</a>, <a href=
-        "scoped_lock.html">scoped_lock</a>, <a href="scoped_try_lock.html">
-        scoped_try_lock</a>, <a href="scoped_timed_lock.html">
-        scoped_timed_lock</a> and <a href="lock_error.html">lock_error</a>.
-        These are considered the &quot;core&quot; synchronization primitives,
-        though there are others that will be added in later phases.</p>
-
-        <h4>Phase 2, Thread Management and Thread Specific Storage</h4>
-
-        <p>This phase addresses the creation and management of threads and
-        provides a mechanism for thread specific storage (data associated with
-        a thread instance). Thread management is a tricky issue in C++, so this
-        phase addresses only the basic needs of multi-threaded program. Later
-        phases are likely to add additional functionality in this area. This
-        phase of <b>Boost.Threads</b> adds the <a href="thread.html">thread</a>
-        and <a href="thread_specific_ptr.html">thread_specific_ptr</a> types.
-        With these additions the <b>Boost.Threads</b> library can be considered
-        minimal but complete.</p>
-
-        <h4>The Next Phase</h4>
-
-        <p>The next phase will address more advanced synchronization concepts,
-        such as read/write mutexes and barriers.</p>

-
-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>The lock concepts provide exception safe means for locking and
-        unlocking a <a href="mutex_concept.html">mutex model</a>. In other
-        words they are an implementation of the <i>Scoped Locking</i> <a href=
-        "bibliography.html#Schmidt 00">[Schmidt 00]</a> pattern. The <a href=
-        "#ScopedLock">ScopedLock</a> concept, with <a href="#ScopedTryLock">
-        ScopedTryLock</a> and <a href="#ScopedTimedLock">ScopedTimedLock</a>
-        refinements, formalize the requirements.</p>
-
-        <p>Lock models are constructed with a reference to a <a href=
-        "mutex_concept.html">mutex model</a> and typically acquire ownership of
-        the <a href="mutex_concept.html">mutex model</a> by setting its state
-        to locked. They also ensure ownership is relinquished in the
-        destructor. Lock models also expose functions to query the lock status
-        and to manually lock and unlock the <a href="mutex_concept.html">mutex
-        model</a>.</p>
-
-        <p>Instances of lock models are meant to be short lived, expected to be
-        used at block scope only. The lock models are not <a href=
-        "definitions.html#Thread-safe">thread-safe</a>. Lock models must
-        maintain state to indicate whether or not they&#39;ve been locked and
-        this state is not protected by any synchronization concepts. For this
-        reason an instance of a lock model should never be shared between
-        multiple threads.</p>

-        <h2>Concept <a name="Requirements">Requirements</a></h2>
-
-        <p>[For documentation purposes, portions of the concept requirements
-        are repeated in the documentation for specific lock classes. Those
-        copies need to be kept in sync with the requirements here.]</p>

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>A mutex (short for mutual-exclusion) concept serializes access to a
-        resource shared between multiple threads. The <a href="#Mutex">
-        Mutex</a> concept, with <a href="#TryMutex">TryMutex</a> and <a href=
-        "#TimedMutex">TimedMutex</a> refinements, formalize the requirements. A
-        model that implements Mutex and its refinements has two states: <b>
-        locked</b> and <b>unlocked</b>. Before using a shared resource, a
-        thread locks a Boost.Threads mutex model object, insuring <a href=
-        "definitions.html#Thread-safe">thread-safe</a> access to the shared
-        resource. When use of the shared resource is complete, the thread
-        unlocks the mutex model object, allowing another thread to acquire the
-        lock and use the shared resource.</p>
-
-        <p>Traditional C thread APIs, like Pthreads or the Windows thread APIs,
-        expose functions to lock and unlock a mutex model. This is dangerous
-        since it&#39;s easy to forget to unlock a locked mutex. When the flow
-        of control is complex, with multiple return points, the likelihood of
-        forgetting to unlock a mutex model would become even greater. When
-        exceptions are thrown, it becomes nearly impossible to ensure that the
-        mutex is unlocked properly when using these traditional API&#39;s. The
-        result is <a href="definitions.html#Deadlock">deadlock</a>.</p>
-
-        <p>Many C++ threading libraries use a pattern known as <i>Scoped
-        Locking</i> <a href="bibliography.html#Schmidt 00">[Schmidt 00]</a> to
-        free the programmer from the need to explicitly lock and unlock
-        mutexes. With this pattern, a <a href="lock_concept.html">lock
-        concept</a> is employed where the lock model&#39;s constructor locks
-        the associated mutex model and the destructor automatically does the
-        unlocking. The <b>Boost.Threads</b> library takes this pattern to the
-        extreme in that lock concepts are the only way to lock and unlock a
-        mutex model: lock and unlock functions are not exposed by any <b>
-        Boost.Threads</b> mutex models. This helps to ensure safe usage
-        patterns, especially when code throws exceptions.</p>
-
-        <h2><a name="LockingStrategies">Locking Strategies</a></h2>
-
-        <p>Every mutex model follows one of several locking strategies. These
-        strategies define the semantics for the locking operation when the
-        calling thread already owns a lock on the mutex model.</p>
-
-        <h3><a name="Recursive">Recursive</a></h3>
-
-        <p>With a recursive locking strategy when a thread attempts to acquire
-        a lock on the mutex model for which it already owns a lock, the
-        operation is successful. Note the distinction between a thread, which
-        may have multiple locks outstanding on a recursive mutex, and a lock
-        object, which even for a recursive mutex cannot have its lock()
-        function called multiple times without first calling unlock().</p>
-
-        <p>Internally a lock count is maintained and the owning thread must
-        unlock the mutex model the same number of times that it&#39;s locked it
-        before the mutex model&#39;s state returns to unlocked. Since mutex
-        models in <b>Boost.Threads</b> expose locking functionality only
-        through lock concepts, a thread will always unlock a mutex model the
-        same number of times that it locked it. This helps to eliminate a whole
-        set of errors typically found in traditional C style thread APIs.</p>
-
-        <p>Classes <a href="recursive_mutex.html">recursive_mutex</a>, <a href=
-        "recursive_mutex.html">recursive_try_mutex</a> and <a href=
-        "recursive_mutex.html">recursive_timed_mutex</a> use this locking
-        strategy.</p>
-
-        <h3><a name="CheckedStrategy">Checked</a></h3>
-
-        <p>With a checked locking strategy when a thread attempts to acquire a
-        lock on the mutex model for which the thread already owns a lock, the
-        operation will fail with some sort of error indication. Further,
-        attempts by a thread to unlock a mutex that was not locked by the
-        thread will also return some sort of error indication. In <b>
-        Boost.Threads</b>, an exception of type <a href="lock_error.html">
-        lock_error</a> would be thrown in these cases.</p>
-
-        <p><b>Boost.Threads</b> does not currently provide any mutex models
-        that use this strategy.</p>
-
-        <h3><a name="UncheckedStrategy">Unchecked</a></h3>
-
-        <p>With an unchecked locking strategy when a thread attempts to acquire
-        a lock on the mutex model for which the thread already owns a lock the
-        operation will <a href="definitions.html#Deadlock">deadlock</a>. In
-        general this locking strategy is less safe than a checked or recursive
-        strategy, but it&#39;s also a faster strategy and so is employed by
-        many libraries.</p>
-
-        <p><b>Boost.Threads</b> does not currently provide any mutex models
-        that use this strategy.</p>
-
-        <h3><a name="UnspecifiedStrategy">Unspecified</a></h3>

-        <p>With an unspecified locking strategy, when a thread attempts to
-        acquire a lock on a mutex model for which the thread already owns a
-        lock the operation results in <b>undefined behavior</b>. When a mutex
-        model has an unspecified locking strategy the programmer must assume
-        that the mutex model instead uses an unchecked strategy.</p>
-
-        <p>In general a mutex model with an unspecified locking strategy is
-        unsafe, and it requires programmer discipline to use the mutex model
-        properly. However, this strategy allows an implementation to be as fast
-        as possible with no restrictions on its implementation. This is
-        especially true for portable implementations that wrap the native
-        threading support of a platform. For this reason, the classes <a href=
-        "mutex.html">mutex</a>, <a href="mutex.html">try_mutex</a> and <a href=
-        "mutex.html">timed_mutex</a> use this locking strategy despite the lack
-        of safety.</p>
-
-        <h2><a name="SchedulingPolicies">Scheduling Policies</a></h2>
-
-        <p>Every mutex model follows one of several scheduling policies. These
-        policies define the semantics when the mutex model is unlocked and
-        there is more than one thread waiting to acquire a lock. In other
-        words, the policy defines which waiting thread shall acquire the
-        lock.</p>
-
-        <h3><a name="FIFO">FIFO</a></h3>
-
-        <p>With a FIFO scheduling policy, threads waiting for the lock will
-        acquire it in a first come first serve order (or First In First Out).
-        This can help prevent a high priority thread from starving lower
-        priority threads that are also waiting on the mutex lock.</p>
-
-        <h3><a name="Priority Driven">Priority Driven</a></h3>
-
-        <p>With a Priority Driven scheduling policy, the thread with the
-        highest priority acquires the lock. Note that this means that
-        low-priority threads may never acquire the lock if the mutex model has
-        high contention and there is always at least one high-priority thread
-        waiting. This is known as thread starvation. When multiple threads of
-        the same priority are waiting on the mutex lock one of the other
-        scheduling priorities will determine which thread shall acquire the
-        lock.</p>
-
-        <h3><a name="UndefinedScheduling">Undefined</a></h3>
-
-        <p>Threads acquire the lock in no particular order. Users should assume
-        that low-priority threads may wait indefinitely, and that threads of
-        the same priority acquire the lock in essentially random order.</p>
-
-        <h3><a name="UnspecifiedScheduling">Unspecified</a></h3>
-
-        <p>The mutex model does not specify which scheduling policy is used.
-        The programmer must assume that an undefined scheduling policy is used.
-        In order to ensure portability, all <b>Boost.Threads</b> mutex models
-        use an unspecified scheduling policy.</p>

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>Boost.Threads allows C++ programs to execute as multiple,
-        asynchronous, independent, threads-of-execution. Each thread has its
-        own machine state including program instruction counter and registers.
-        Programs which execute as multiple threads are called multi-threaded
-        programs to distinguish them from traditional single-threaded programs.
-        <a href="definitions.html">Definitions</a> gives a more complete
-        description of the multi-threading execution environment.</p>
-
-        <p>Multi-threading provides several advantages:</p>
-
-        <ul>
-            <li>Programs which would otherwise block waiting for some external
-            event can continue to respond if the blocking operation is placed
-            in a separate thread. Multi-threading is usually an absolute
-            requirement for these programs.</li>
-        </ul>
-
-        <ul>
-            <li>Well-designed multi-threaded programs may execute faster than
-            single-threaded programs, particularly on multi-processor hardware.
-            Note, however, that poorly-designed multi-threaded programs are
-            often slower that single-threaded programs.</li>
-        </ul>
-
-        <ul>
-            <li>Some program designs may be easier to formulate using a
-            multi-threaded approach. After all, the real world is
-            asynchronous!</li>
-        </ul>
-
-        <h2><a name="Dangers">Dangers</a></h2>
-
-        <p>Beyond the errors which can occur in single-threaded programs,
-        multi-threaded programs are subject to additional errors:</p>
-
-        <ul>
-            <li><a href="definitions.html#Race condition">Race
-            conditions</a>.</li>
-
-            <li><a href="definitions.html#Deadlock">Deadlock</a> (sometimes
-            called &quot;deadly embrace&quot;)</li>
-
-            <li><a href="definitions.html#Priority failure">Priority
-            failures</a> (priority inversion, infinite overtaking, starvation,
-            etc.)</li>
-        </ul>
-
-        <p>Every multi-threaded program must be designed carefully to avoid
-        race conditions and deadlock. These aren&#39;t rare or exotic failures
-        - they are virtually guaranteed to occur unless multi-threaded code is
-        designed to avoid them. Priority failures are somewhat less common, but
-        are none-the-less serious.</p>
-
-        <p>The <a href="introduction.html">Boost.Threads design</a> attempts to
-        minimize these errors, but they will still occur unless the programmer
-        proactively designs to avoid them.</p>
-
-        <h3>Testing and debugging considerations</h3>
-
-        <p>Multi-threaded programs are non-deterministic. In other words, the
-        same program with the same input data may follow different execution
-        paths each time it is invoked. That can make testing and debugging a
-        nightmare:</p>
-
-        <ul>
-            <li>Failures are often not repeatable.</li>
-
-            <li>Probe effect causes debuggers to produce very different results
-            from non-debug uses.</li>
-
-            <li>Debuggers require special support to show thread state.</li>
-
-            <li>Tests on a single processor system may give no indication of
-            serious errors which would appear on multiprocessor systems, and
-            visa versa. Thus test cases should include a varying number of
-            processors.</li>
-
-            <li>For programs which create a varying number of threads according
-            to workload, tests which don&#39;t span the full range of
-            possibilities may miss serious errors.</li>
-        </ul>
-
-        <h3>Getting a head start</h3>
-
-        <p>Although it might appear that multi-threaded programs are inherently
-        unreliable, many reliable multi-threaded programs do exist.
-        Multi-threading techniques are known which lead to reliable
-        programs.</p>
-
-        <p>Design patterns for reliable multi-threaded programs, including the
-        important <i>monitor</i> pattern, are presented in <cite>
-        Pattern-Oriented Software Architecture Volume 2 - Patterns for
-        Concurrent and Networked Objects</cite> [<a href=
-        "bibliography.html#Schmidt-00">Schmidt 00</a>]. Many important
-        multi-threading programming considerations (independent of threading
-        library) are discussed in <cite>Programming with POSIX Threads</cite>
-        [<a href="bibliography.html#Butenhof-97">Butenhof 97</a>].</p>
-
-        <p>Doing some reading before attempting multi-threaded designs will give
-        you a head start toward reliable multi-threaded programs.</p>
-
-        <h2><a name="Library">C++ Standard Library usage in multi-threaded
-        programs</a></h2>
-
-        <h3>Runtime libraries</h3>
-
-        <p><b>Warning:</b> Multi-threaded programs such as those using <b>
-        Boost.Threads</b> must link to <a href="definitions.html#Thread-safe">
-        thread-safe</a> versions of all runtime libraries used by the program,
-        including the runtime library for the C++ Standard Library. Otherwise
-        <a href="definitions.html#Race condition">race conditions</a> will
-        occur when multiple threads simultaneously execute runtime library
-        functions for <i>new</i>, <i>delete</i>, or other language features
-        which imply shared state.</p>
-
-        <h3>Potentially non-thread-safe functions</h3>
-
-        <p>Certain C++ Standard Library functions inherited from C are
-        particular problems because they hold internal state between calls:</p>
-
-        <ul>
-            <li>rand</li>
-
-            <li>strtok</li>
-
-            <li>asctime</li>
-
-            <li>ctime</li>
-
-            <li>gmtime</li>
-
-            <li>localtime</li>
-        </ul>
-
-        <p>It is possible to write thread-safe implementations of these by
-        using <a href="thread_specific_ptr.html">thread-specific storage</a>,
-        and several C++ compiler vendors do just that. The technique is
-        well-know and is explained in [<a href=
-        "bibliography.html#Butenhof-97">Buttenhof-97</a>].</p>
-
-        <p>But at least one vendor (HP-UX) does not provide thread-safe
-        implementations of the above functions in their otherwise thread-safe
-        runtime library. Instead they provide replacement functions with
-        different names and arguments.</p>
-
-        <p><b>Recommendation:</b> For the most portable, yet thread-safe code,
-        use Boost replacements for the problem functions. See the <a href=
-        "../../random/index.html">Boost Random Number Library</a> and <a href=
-        "../../tokenizer/index.htm">Boost Tokenizer Library</a>.</p>
-
-        <h2><a name="Common">Common</a> requirements for all Boost.Threads
-        components</h2>
-
-        <h3>Exceptions</h3>
-
-        <p><b>Boost.Threads</b> destructors never throw exceptions. Unless
-        otherwise specified, other <b>Boost.Threads</b> functions that do not
-        have an exception-specification may throw implementation-defined
-        exceptions.</p>
-

-
-        <p>This page explains the rationale behind various design decisions in
-        the <b>Boost.Threads</b> library. Having the rationale documented here
-        should explain how we arrived at the current design as well as prevent
-        future rehashing of discussions and thought processes that have already
-        occurred. It can also give users a lot of insight into the design
-        process required for this library.</p>
-
-        <h2><a name="library">Rationale for the Creation of
-        Boost.Threads</a></h2>
-
-        <p>Processes often have a degree of &quot;potential parallelism&quot;
-        and it can often be more intuitive to design systems with this in mind.
-        Further, these parallel processes can result in more responsive
-        programs. The benefits for multi-threaded programming are quite well
-        known to most modern programmers, yet the C++ language doesn&#39;t
-        directly support this concept.</p>
-
-        <p>Many platforms support multi-threaded programming despite the fact
-        that the language doesn&#39;t support it. They do this through external
-        libraries, which are, unfortunately, platform specific. POSIX has tried
-        to address this problem through the standardization of a
-        &quot;pthread&quot; library. However, this is a standard only on POSIX
-        platforms, so its portability is limited.</p>
-
-        <p>Another problem with POSIX and other platform specific thread
-        libraries is that they are almost universally C based libraries. This
-        leaves several C++ specific issues unresolved, such as what happens
-        when an exception is thrown in a thread. Further, there are some C++
-        concepts, such as destructors, that can make usage much easier than
-        what&#39;s available in a C library.</p>
-
-        <p>What&#39;s truly needed is C++ language support for threads.
-        However, the C++ standards committee needs existing practice or a good
-        proposal as a starting point for adding this to the standard.</p>
-
-        <p>The Boost.Threads library was developed to provide a C++ developer
-        with a portable interface for writing multi-threaded programs on
-        numerous platforms. There&#39;s a hope that the library can be the
-        basis for a more detailed proposal for the C++ standards committee to
-        consider for inclusion in the next C++ standard.</p>
-
-        <h2><a name="primitives">Rationale for the Low Level Primitives
-        Supported in Boost.Threads</a></h2>
-
-        <p>The Boost.Threads library supplies a set of low level primitives for
-        writing multi-threaded programs, such as mutexes and condition variables.
-        In fact, the first release of Boost.Threads supports only these low level
-        primitives. However, computer science research has shown that use of these
-        primitives is difficult since there&#39;s no way to mathematically prove
-        that a usage pattern is correct, meaning it doesn&#39;t result in race
-        conditions or deadlocks. There are several algebras (such as CSP, CCS and
-        Join calculus) that have been developed to help write provably correct
-        parallel processes. In order to prove the correctness these processes must
-        be coded using higher level abstractions. So why does Boost.Threads support
-        the lower level concepts?</p>
-
-        <p>The reason is simple: the higher level concepts need to be
-        implemented using at least some of the lower level concepts. So having
-        portable lower level concepts makes it easier to develop the higher
-        level concepts and will allow researchers to experiment with various
-        techniques.</p>
-
-        <p>Beyond this theoretical application of higher level concepts,
-        however, the fact remains that many multi-threaded programs are written
-        using only the lower level concepts, so they are useful in and of
-        themselves, even if it&#39;s hard to prove that their usage is correct.
-        Since many users will be familiar with these lower level concepts but
-        be unfamiliar with any of the higher level concepts there&#39;s also an
-        argument for accessibility.</p>
-
-        <h2><a name="lock_objects">Rationale for the Lock Design</a></h2>
-
-        <p>Programmers who are used to multi-threaded programming issues will
-        quickly note that the Boost.Thread&#39;s design for mutex lock concepts
-        is not <a href="definitions.html#Thread-safe">thread-safe</a> (this is
-        clearly documented as well). At first this may seem like a serious
-        design flaw. Why have a multi-threading primitive that&#39;s not
-        thread-safe itself?</p>
-
-        <p>A lock object is not a synchronization primitive. A lock
-        object&#39;s sole responsibility is to ensure that a mutex is both
-        locked and unlocked in a manner that won&#39;t result in the common
-        error of locking a mutex and then forgetting to unlock it. This means
-        that instances of a lock object are only going to be created, at least
-        in theory, within block scope and won&#39;t be shared between threads.
-        Only the mutex objects will be created outside of block scope and/or
-        shared between threads. Though it&#39;s possible to create a lock
-        object outside of block scope and to share it between threads to do so
-        would not be a typical usage. Nor are there any cases when such usage
-        would be required.</p>
-
-        <p>Lock objects must maintain some state information. In order to allow
-        a program to determine if a try_lock or timed_lock was successful the
-        lock object must retain state indicating the success or failure of the
-        call made in its constructor. If a lock object were to have such state
-        and remain thread-safe it would need to synchronize access to the state
-        information which would result in roughly doubling the time of most
-        operations. Worse, since checking the state can occur only by a call
-        after construction we&#39;d have a race condition if the lock object
-        were shared between threads.</p>
-
-        <p>So, to avoid the overhead of synchronizing access to the state
-        information and to avoid the race condition the Boost.Threads library
-        simply does nothing to make lock objects thread-safe. Instead, sharing
-        a lock object between threads results in undefined behavior. Since the
-        only proper usage of lock objects is within block scope this isn&#39;t
-        a problem, and so long as the lock object is properly used there&#39;s
-        no danger of any multi-threading issues.</p>
-
-        <h2><a name="thread">Rationale for Non-copyable Thread Type</a></h2>
-
-        <p>Programmers who are used to C libraries for multi-threaded
-        programming are likely to wonder why Boost.Threads uses a non-copyable
-        design for <a href="thread.html">boost::thread</a>. After all, the C
-        thread types are copyable, and you often have a need for copying them
-        within user code. However, careful comparison of C designs to C++
-        designs shows a flaw in this logic.</p>
-
-        <p>All C types are copyable. It is, in fact, not possible to make a
-        non-copyable type in C. For this reason types that represent system
-        resources in C are often designed to behave very similarly to a pointer
-        to dynamic memory. There&#39;s an API for acquiring the resource and an
-        API for releasing the resources. For memory we have pointers as the
-        type and alloc/free for the acquisition and release APIs. For files we
-        have FILE* as the type and fopen/fclose for the acquisition and release
-        APIs. You can freely copy instances of the types but must manually
-        manage the lifetime of the actual resource through the acquisition and
-        release APIs.</p>
-
-        <p>C++ designs recognize that the acquisition and release APIs are
-        error prone and try to eliminate possible errors by acquiring the
-        resource in the constructor and releasing it in the destructor. The
-        best example of such a design is the std::iostream set of classes which
-        can represent the same resource as the FILE* type in C. A file is
-        opened in the std::fstream&#39;s constructor and closed in its
-        destructor. However, if an iostream were copyable it could lead to a
-        file being closed twice, an obvious error, so the std::iostream types
-        are noncopyable by design. This is the same design used by
-        boost::thread, which is a simple and easy to understand design
-        that&#39;s consistent with other C++ standard types.</p>
-
-        <p>During the design of boost::thread it was pointed out that it would
-        be possible to allow it to be a copyable type if some form of
-        &quot;reference management&quot; were used, such as ref-counting or
-        ref-lists, and many argued for a boost::thread_ref design instead. The
-        reasoning was that copying &quot;thread&quot; objects was a typical
-        need in the C libraries, and so presumably would be in the C++
-        libraries as well. It was also thought that implementations could
-        provide more efficient reference management then wrappers (such as
-        boost::shared_ptr) around a noncopyable thread concept. Analysis of
-        whether or not these arguments would hold true don&#39;t appear to bear
-        them out. To illustrate the analysis we&#39;ll first provide
-        pseudo-code illustrating the six typical usage patterns of a thread
-        object.</p>

-
-        <p>Of these usage patterns there&#39;s only one that requires reference
-        management (number 6). Hopefully it&#39;s fairly obvious that this
-        usage pattern simply won&#39;t occur as often as the other usage
-        patterns. So there really isn&#39;t a &quot;typical need&quot; for a
-        thread concept, though there is some need.</p>
-
-        <p>Since the need isn&#39;t typical we must use different criteria for
-        deciding on either a thread_ref or thread design. Possible criteria
-        include ease of use and performance. So let&#39;s analyze both of these
-        carefully.</p>
-
-        <p>With ease of use we can look at existing experience. The standard
-        C++ objects that represent a system resource, such as std::iostream,
-        are noncopyable, so we know that C++ programmers must at least be
-        experienced with this design. Most C++ developers are also used to
-        smart pointers such as boost::shared_ptr, so we know they can at least
-        adapt to a thread_ref concept with little effort. So existing
-        experience isn&#39;t going to lead us to a choice.</p>
-
-        <p>The other thing we can look at is how difficult it is to use both
-        types for the six usage patterns above. If we find it overly difficult
-        to use a concept for any of the usage patterns there would be a good
-        argument for choosing the other design. So we&#39;ll code all six usage
-        patterns using both designs.</p>

-</pre>
-
-        <p>This shows the usage patterns being nearly identical in complexity
-        for both designs. The only actual added complexity occurs because of
-        the use of operator new in (4), (5) and (6) and the use of
-        std::auto_ptr and boost::shared_ptr in (4) and (6) respectively.
-        However, that&#39;s not really much added complexity, and C++
-        programmers are used to using these idioms any way. Some may dislike
-        the presence of operator new in user code, but this can be eliminated
-        by proper design of higher level concepts, such as the
-        boost::thread_group class that simplifies example (4) down to:</p>
-<pre>
-void foo()
-{
-   thread_group threads;
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      threads.create_thread(&amp;bar);
-   threads.join_all();
-}
-</pre>
-
-        <p>So ease of use is really a wash and not much help in picking a
-        design.</p>
-
-        <p>So what about performance? If you look at the above code examples we
-        can analyze the theoretical impact to performance that both designs
-        have. For (1) we can see that platforms that don&#39;t have a
-        ref-counted native thread type (POSIX, for instance) will be impacted
-        by a thread_ref design. Even if the native thread type is ref-counted
-        there may be an impact if more state information has to be maintained
-        for concepts foreign to the native API, such as clean up stacks for
-        Win32 implementations. For (2) the performance impact will be identical
-        to (1). The same for (3). For (4) things get a little more interesting
-        and we find that theoretically at least the thread_ref may perform
-        faster since the thread design requires dynamic memory
-        allocation/deallocation. However, in practice there may be dynamic
-        allocation for the thread_ref design as well, it will just be hidden
-        from the user. As long as the implementation has to do dynamic
-        allocations the thread_ref loses again because of the reference
-        management. For (5) we see the same impact as we do for (4). For (6) we
-        still have a possible impact to the thread design because of dynamic
-        allocation but thread_ref no longer suffers because of it&#39;s
-        reference management, and in fact, theoretically at least, the
-        thread_ref may do a better job of managing the references. All of this
-        indicates that thread wins for (1), (2) and (3), with (4) and (5) the
-        winner depends on the implementation and the platform but the thread
-        design probably has a better chance, and with (6) it will again depend
-        on the implementation and platform but this time we favor thread_ref
-        slightly. Given all of this it&#39;s a narrow margin, but the thread
-        design prevails.</p>
-
-        <p>Given this analysis, and the fact that noncopyable objects for
-        system resources are the normal designs that C++ programmers are used
-        to dealing with, the Boost.Threads library has gone with a noncopyable
-        design.</p>
-
-        <h2>Rationale for not providing <i><a name="Events">Event</a>
-        Variables</i></h2>
-
-        <p><i>Event variables</i> are simply far too error-prone. <a href=
-        "condition.html">Condition variables</a> are a much safer
-        alternative.</p>
-
-        <p>[Note that Graphical User Interface <i>events</i> are a different
-        concept, and are not what is being discussed here.]</p>
-
-        <p>Event variables were one of the first synchronization primitives.
-        They are still used today, for example, in the native Windows
-        multithreading API.</p>
-
-        <p>Yet both respected computer science researchers and experienced
-        multithreading practitioners believe event variables are so inherently
-        error-prone that they should never be used, and thus should not be part
-        of a multithreading library.</p>
-
-        <p>Per Brinch Hansen <a href="bibliography.html#Brinch-Hansen-73">
-        [Brinch Hansen 73]</a> analyzed event variables in some detail,
-        pointing out [emphasis his] that &quot;<i>event operations force the
-        programmer to be aware of the relative speeds of the sending and
-        receiving processes</i>&quot;. His summary:</p>
-
-        <blockquote>
-            <p>We must therefore conclude that event variables of the previous
-            type are impractical for system design. <i>The effect of an
-            interaction between two processes must be independent of the speed
-            at which it is carried out.</i></p>
-        </blockquote>
-
-        <p>Experienced programmers using the Windows platform today report that
-        event variables are a continuing source of errors, even after previous
-        bad experiences caused them to be very careful in their use of event
-        variables. Overt problems can be avoided, for example, by teaming the
-        event variable with a mutex, but that may just convert a <a href=
-        "definitions.html#Race condition">race condition</a> into another
-        problem, such as excessive resource use. One of the most distressing
-        aspects of the experience reports is the claim that many defects are
-        latent. That is, the programs appear to work correctly, but contain
-        hidden timing dependencies which will cause them to fail when
-        environmental factors or usage patterns change, altering relative
-        thread timings.</p>
-
-        <p>The decision to exclude event variables from Boost.Threads has been
-        surprising to some Windows programmers. They have written programs
-        which work using event variables, and wonder what the problem is. It
-        seems similar to the &quot;goto considered harmful&quot; controversy of
-        30 years ago. It isn&#39;t that events, like gotos, can&#39;t be made
-        to work, but rather that virtually all programs using alternatives will
-        be easier to write, debug, read, maintain, and be less likely to
-        contain latent defects.</p>

+  <para>This page explains the rationale behind various design decisions in the
+  &Boost.Threads; library. Having the rationale documented here should explain
+  how we arrived at the current design as well as prevent future rehashing of
+  discussions and thought processes that have already occurred. It can also give
+  users a lot of insight into the design process required for this
+  library.</para>
+  <section id="threads.rationale.Boost.Threads">
+    <title>Rationale for the Creation of &Boost.Threads;</title>
+    <para>Processes often have a degree of "potential parallelism" and it can
+	often be more intuitive to design systems with this in mind. Further, these
+	parallel processes can result in more responsive programs. The benefits for
+	multithreaded programming are quite well known to most modern programmers,
+	yet the C++ language doesn't directly support this concept.</para>
+    <para>Many platforms support multithreaded programming despite the fact that
+	the language doesn't support it. They do this through external libraries,
+	which are, unfortunately, platform specific. POSIX has tried to address this
+	problem through the standardization of a "pthread" library. However, this is
+	a standard only on POSIX platforms, so its portability is limited.</para>
+    <para>Another problem with POSIX and other platform specific thread
+	libraries is that they are almost universally C based libraries. This leaves
+	several C++ specific issues unresolved, such as what happens when an
+	exception is thrown in a thread. Further, there are some C++ concepts, such
+	as destructors, that can make usage much easier than what's available in a C
+	library.</para>
+    <para>What's truly needed is C++ language support for threads. However, the
+	C++ standards committee needs existing practice or a good proposal as a
+	starting point for adding this to the standard.</para>
+    <para>The &Boost.Threads; library was developed to provide a C++ developer
+	with a portable interface for writing multithreaded programs on numerous
+	platforms. There's a hope that the library can be the basis for a more
+	detailed proposal for the C++ standards committee to consider for inclusion
+	in the next C++ standard.</para>
+  </section>
+  <section id="threads.rationale.primitives">
+    <title>Rationale for the Low Level Primitives Supported in &Boost.Threads;</title>
+    <para>The &Boost.Threads; library supplies a set of low level primitives for
+	writing multithreaded programs, such as mutexes and condition variables. In
+	fact, the first release of &Boost.Threads; supports only these low level
+	primitives. However, computer science research has shown that use of these
+	primitives is difficult since it's difficult to mathematically prove that a
+	usage pattern is correct, meaning it doesn't result in race conditions or
+	deadlocks. There are several algebras (such as CSP, CCS and Join calculus)
+	that have been developed to help write provably correct parallel
+	processes. In order to prove the correctness these processes must be coded
+	using higher level abstractions. So why does &Boost.Threads; support the
+	lower level concepts?</para>
+    <para>The reason is simple: the higher level concepts need to be implemented
+	using at least some of the lower level concepts. So having portable lower
+	level concepts makes it easier to develop the higher level concepts and will
+	allow researchers to experiment with various techniques.</para>
+    <para>Beyond this theoretical application of higher level concepts, however,
+	the fact remains that many multithreaded programs are written using only the
+	lower level concepts, so they are useful in and of themselves, even if it's
+	hard to prove that their usage is correct. Since many users will be familiar
+	with these lower level concepts but unfamiliar with any of the higher
+	level concepts, supporting the lower level concepts provides
+	greater accessibility.</para>
+  </section>
+  <section id="threads.rationale.locks">
+    <title>Rationale for the Lock Design</title>
+    <para>Programmers who are used to multithreaded programming issues will
+	quickly note that the &Boost.Threads; design for mutex lock concepts is not
+	<link linkend="threads.glossary.thread-safe">thread-safe</link> (this is
+	clearly documented as well). At first this may seem like a serious design
+	flaw. Why have a multithreading primitive that's not thread-safe
+	itself?</para>
+    <para>A lock object is not a synchronization primitive. A lock object's sole
+	responsibility is to ensure that a mutex is both locked and unlocked in a
+	manner that won't result in the common error of locking a mutex and then
+	forgetting to unlock it. This means that instances of a lock object are only
+	going to be created, at least in theory, within block scope and won't be
+	shared between threads. Only the mutex objects will be created outside of
+	block scope and/or shared between threads. Though it's possible to create a
+	lock object outside of block scope and to share it between threads, to do so
+	would not be a typical usage (in fact, to do so would likely be an
+	error). Nor are there any cases when such usage would be required.</para>
+    <para>Lock objects must maintain some state information. In order to allow a
+	program to determine if a try_lock or timed_lock was successful the lock
+	object must retain state indicating the success or failure of the call made
+	in its constructor. If a lock object were to have such state and remain
+	thread-safe it would need to synchronize access to the state information
+	which would result in roughly doubling the time of most operations. Worse,
+	since checking the state can occur only by a call after construction, we'd
+	have a race condition if the lock object were shared between threads.</para>
+    <para>So, to avoid the overhead of synchronizing access to the state
+	information and to avoid the race condition, the &Boost.Threads; library
+	simply does nothing to make lock objects thread-safe. Instead, sharing a
+	lock object between threads results in undefined behavior. Since the only
+	proper usage of lock objects is within block scope this isn't a problem, and
+	so long as the lock object is properly used there's no danger of any
+	multithreading issues.</para>
+  </section>
+  <section id="threads.rationale.non-copyable">
+    <title>Rationale for NonCopyable Thread Type</title>
+    <para>Programmers who are used to C libraries for multithreaded programming
+	are likely to wonder why &Boost.Threads; uses a noncopyable design for
+	<classname>boost::thread</classname>. After all, the C thread types are
+	copyable, and you often have a need for copying them within user
+	code. However, careful comparison of C designs to C++ designs shows a flaw
+	in this logic.</para>
+    <para>All C types are copyable. It is, in fact, not possible to make a
+	noncopyable type in C. For this reason types that represent system resources
+	in C are often designed to behave very similarly to a pointer to dynamic
+	memory. There's an API for acquiring the resource and an API for releasing
+	the resource. For memory we have pointers as the type and alloc/free for
+	the acquisition and release APIs. For files we have FILE* as the type and
+	fopen/fclose for the acquisition and release APIs. You can freely copy
+	instances of the types but must manually manage the lifetime of the actual
+	resource through the acquisition and release APIs.</para>
+    <para>C++ designs recognize that the acquisition and release APIs are error
+	prone and try to eliminate possible errors by acquiring the resource in the
+	constructor and releasing it in the destructor. The best example of such a
+	design is the std::iostream set of classes which can represent the same
+	resource as the FILE* type in C. A file is opened in the std::fstream's
+	constructor and closed in its destructor. However, if an iostream were
+	copyable it could lead to a file being closed twice, an obvious error, so
+	the std::iostream types are noncopyable by design. This is the same design
+	used by boost::thread, which is a simple and easy to understand design
+	that's consistent with other C++ standard types.</para>
+    <para>During the design of boost::thread it was pointed out that it would be
+	possible to allow it to be a copyable type if some form of "reference
+	management" were used, such as ref-counting or ref-lists, and many argued
+	for a boost::thread_ref design instead. The reasoning was that copying
+	"thread" objects was a typical need in the C libraries, and so presumably
+	would be in the C++ libraries as well. It was also thought that
+	implementations could provide more efficient reference management than
+	wrappers (such as boost::shared_ptr) around a noncopyable thread
+	concept. Analysis of whether or not these arguments would hold true doesn't
+	appear to bear them out. To illustrate the analysis we'll first provide
+	pseudo-code illustrating the six typical usage patterns of a thread
+	object.</para>

+    <para>Of these usage patterns there's only one that requires reference

+	simply won't occur as often as the other usage patterns. So there really
+	isn't a "typical need" for a thread concept, though there is some
+	need.</para>
+    <para>Since the need isn't typical we must use different criteria for
+	deciding on either a thread_ref or thread design. Possible criteria include
+	ease of use and performance. So let's analyze both of these
+	carefully.</para>
+    <para>With ease of use we can look at existing experience. The standard C++

+    <para>The other thing we can look at is how difficult it is to use both
+	types for the six usage patterns above. If we find it overly difficult to
+	use a concept for any of the usage patterns there would be a good argument
+	for choosing the other design. So we'll code all six usage patterns using

+    <para>This shows the usage patterns being nearly identical in complexity for
+	both designs. The only actual added complexity occurs because of the use of
+	operator new in 
+	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>,
+	<link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link>, and
+	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>;
+	and the use of std::auto_ptr and boost::shared_ptr in 
+	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link> and 
+	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>
+	respectively. However, that's not really
+	much added complexity, and C++ programmers are used to using these idioms
+	anyway. Some may dislike the presence of operator new in user code, but
+	this can be eliminated by proper design of higher level concepts, such as
+	the boost::thread_group class that simplifies example 
+	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
+	down to:</para>
+    <programlisting>

+    <para>So ease of use is really a wash and not much help in picking a
+	design.</para>
+    <para>So what about performance? Looking at the above code examples, 
+    we can analyze the theoretical impact to performance that both designs
+	have. For <link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>
+	we can see that platforms that don't have a ref-counted native
+	thread type (POSIX, for instance) will be impacted by a thread_ref
+	design. Even if the native thread type is ref-counted there may be an impact
+	if more state information has to be maintained for concepts foreign to the
+	native API, such as clean up stacks for Win32 implementations. 
+	For <link linkend="threads.rationale_comparison.non-copyable.joined">(2)</link>
+	and <link linkend="threads.rationale_comparison.non-copyable.loop">(3)</link>
+	the performance impact will be identical to
+	<link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>.
+	For <link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
+	things get a little more interesting and we find that theoretically at least
+	the thread_ref may perform faster since the thread design requires dynamic
+	memory allocation/deallocation. However, in practice there may be dynamic
+	allocation for the thread_ref design as well, it will just be hidden from
+	the user. As long as the implementation has to do dynamic allocations the
+	thread_ref loses again because of the reference management. For 
+	<link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link> we see
+	the same impact as we do for 
+	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>.
+	For <link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link>
+	we still have a possible impact to
+	the thread design because of dynamic allocation but thread_ref no longer
+	suffers because of its reference management, and in fact, theoretically at
+	least, the thread_ref may do a better job of managing the references. All of
+	this indicates that thread wins for 
+	<link linkend="threads.rationale_comparison.non-copyable.simple">(1)</link>, 
+	<link linkend="threads.rationale_comparison.non-copyable.joined">(2)</link> and 
+	<link linkend="threads.rationale_comparison.non-copyable.loop">(3)</link>; with 
+	<link linkend="threads.rationale_comparison.non-copyable.loop-join">(4)</link>
+	and <link linkend="threads.rationale_comparison.non-copyable.pass">(5)</link> the
+	winner depending on the implementation and the platform but with the thread design
+	probably having a better chance; and with 
+	<link linkend="threads.rationale_comparison.non-copyable.shared">(6)</link> 
+	it will again depend on the
+	implementation and platform but this time we favor thread_ref
+	slightly. Given all of this it's a narrow margin, but the thread design
+	prevails.</para>
+	<para>Given this analysis, and the fact that noncopyable objects for system
+	resources are the normal designs that C++ programmers are used to dealing
+	with, the &Boost.Threads; library has gone with a noncopyable design.</para>

+    <title>Rationale for not providing <emphasis>Event Variables</emphasis></title>
+    <para><emphasis>Event variables</emphasis> are simply far too
+	error-prone. <classname>boost::condition</classname> variables are a much safer
+	alternative. [Note that Graphical User Interface <emphasis>events</emphasis> are 
+	a different concept, and are not what is being discussed here.]</para>
+    <para>Event variables were one of the first synchronization primitives. They
+	are still used today, for example, in the native Windows multithreading
+	API. Yet both respected computer science researchers and experienced
+	multithreading practitioners believe event variables are so inherently
+	error-prone that they should never be used, and thus should not be part of a
+	multithreading library.</para>
+    <para>Per Brinch Hansen &cite.Hansen73; analyzed event variables in some
+	detail, pointing out [emphasis his] that "<emphasis>event operations force
+	the programmer to be aware of the relative speeds of the sending and
+	receiving processes</emphasis>". His summary:</para>
+    <blockquote>
+      <para>We must therefore conclude that event variables of the previous type
+	  are impractical for system design. <emphasis>The effect of an interaction
+	  between two processes must be independent of the speed at which it is
+	  carried out.</emphasis></para>
+    </blockquote>
+    <para>Experienced programmers using the Windows platform today report that
+	event variables are a continuing source of errors, even after previous bad
+	experiences caused them to be very careful in their use of event
+	variables. Overt problems can be avoided, for example, by teaming the event
+	variable with a mutex, but that may just convert a <link
+	linkend="threads.glossary.race-condition">race condition</link> into another
+	problem, such as excessive resource use. One of the most distressing aspects
+	of the experience reports is the claim that many defects are latent. That
+	is, the programs appear to work correctly, but contain hidden timing
+	dependencies which will cause them to fail when environmental factors or
+	usage patterns change, altering relative thread timings.</para>
+    <para>The decision to exclude event variables from &Boost.Threads; has been
+	surprising to some Windows programmers. They have written programs which
+	work using event variables, and wonder what the problem is. It seems similar
+	to the "goto considered harmful" controversy of 30 years ago. It isn't that
+	events, like gotos, can't be made to work, but rather that virtually all
+	programs using alternatives will be easier to write, debug, read, maintain,
+	and will be less likely to contain latent defects.</para>

-
-        <p>The <code>recursive_mutex</code>, <code>recursive_try_mutex</code>
-        and <code>recursive_timed_mutex</code> classes define full featured
-        models of the <a href="mutex_concept.html#Mutex">Mutex</a>, <a href=
-        "mutex_concept.html#TryMutex">TryMutex</a> and <a href=
-        "mutex_concept.html#TimedMutex">TimedMutex</a> concepts with recursive
-        locking semantics. These types should be used to synchronize access to
-        shared resources when recursive locking by a single thread is likely to
-        occur. A good example for this is when a class supplies &quot;internal
-        synchronization&quot; to ensure <a href="definitions.html#Thread-safe">
-        thread-safety</a> and a function of the class may have to call other
-        functions of the class which also attempt to lock the mutex. For
-        recursive locking mechanics, see <a href="mutex.html">mutexes</a>.</p>
-
-        <p>Each class supplies one or more typedefs for lock types which model
-        matching lock concepts. For the best possible performance you should
-        use the mutex class that supports the minimum set of lock types that
-        you need.</p>

+			<title>Statically-link build option added</title>
+
+			<para>The option to link &Boost.Threads; as a static
+			library has been added (with some limitations on Win32 platforms).
+			This feature was originally removed from an earlier version
+			of Boost because <classname>boost::thread_specific_ptr</classname>
+			required that &Boost.Threads; be dynamically linked in order
+			for its cleanup functionality to work on Win32 platforms.
+			Because this limitation never applied to non-Win32 platforms,
+			because significant progress has been made in removing
+			the limitation on Win32 platforms (many thanks to
+			Aaron LaFramboise and Roland Scwarz!), and because the lack
+			of static linking is one of the most common complaints of
+			&Boost.Threads; users, this decision was reversed.</para>
+			
+			<para>On non-Win32 platforms: 
+			To choose the dynamically linked version of &Boost.Threads; 
+			using Boost's auto-linking feature, #define BOOST_THREAD_USE_DLL;
+			to choose the statically linked version, 
+			#define BOOST_THREAD_USE_LIB. 
+			If neither symbols is #defined, the default will be chosen.
+			Currently the default is the statically linked version.</para>
+			
+			<para>On Win32 platforms using VC++: 
+			Use the same #defines as for non-Win32 platforms 
+			(BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB).
+			If neither is #defined, the default will be chosen. 
+			Currently the default is the statically linked version
+			if the VC++ run-time library is set to
+			"Multi-threaded" or "Multi-threaded Debug", and
+			the dynamically linked version
+			if the VC++ run-time library is set to 
+			"Multi-threaded DLL" or "Multi-threaded Debug DLL".</para>
+			
+			<para>On Win32 platforms using compilers other than VC++:
+			Use the same #defines as for non-Win32 platforms 
+			(BOOST_THREAD_USE_DLL and BOOST_THREAD_USE_LIB).
+			If neither is #defined, the default will be chosen. 
+			Currently the default is the dynamically linked version
+			because it has not yet been possible to implement automatic
+			tss cleanup in the statically linked version for compilers
+			other than VC++, although it is hoped that this will be
+			possible in a future version of &Boost.Threads;.
+			
+			Note for advanced users: &Boost.Threads; provides several "hook"
+			functions to allow users to experiment with the statically
+			linked version on Win32 with compilers other than VC++.
+			These functions are on_process_enter(), on_process_exit(),
+			on_thread_enter(), and on_thread_exit(), and are defined
+			in tls_hooks.cpp. See the comments in that file for more
+			information.</para>

-        and <a href="recursive_mutex.html">recursive_timed_mutex</a> classes
-        use this template to define their <code>scoped_try_lock</code>
-        types.</p>
-
-        <p>Like all the <b>Boost.Threads</b> <a href="lock_concept.html">lock
-        models</a>, <code>scoped_try_lock</code> objects are meant to be
-        short-lived. Objects of the class are not <a href=
-        "definitions.html#thread-safe">thread-safe</a>, and so should not be
-        shared between threads.</p>
-
-        <p>Class <code>scoped_try_lock</code> follows the &quot;resource
-        acquisition is initialization&quot; idiom <a href=
-        "bibliography.html#Stroustrup-00">[Stroustrup 00 14.4.1]</a> and is a
-        realization of the &quot;Scoped Locking Pattern&quot; <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a>. Thus the usage is to
-        let the constructor do the locking, and then let the destructor do the
-        unlocking automatically at the end of the enclosing scope. The lock()
-        and unlock() members are usually not explicitly called, but are
-        provided to allow for complex overlapping locks of multiple
-        mutexes.</p>
-
-        <p>Although this class is an implementation detail, it is publicly
-        documented here because of its importance.</p>
-
-        <p>The type used to instantiate the class must meet the <a href=
-        "mutex_concept.html#TryMutex">TryMutex</a> requirements.</p>

+		<purpose>
+			<para>The <classname>thread</classname> class represents threads of
+			execution, and provides the functionality to create and manage 
+			threads within the &Boost.Threads; library. See 
+			<xref linkend="threads.glossary"/> for a precise description of 
+			<link linkend="threads.glossary.thread">thread of execution</link>,
+			and for definitions of threading-related terms and of thread states such as 
+			<link linkend="threads.glossary.thread-state">blocked</link>.</para>
+		</purpose>
+
+		<description>
+			<para>A <link linkend="threads.glossary.thread">thread of execution</link>
+			has an initial function. For the program's initial thread, the initial 
+			function is <code>main()</code>. For other threads, the initial 
+			function is <code>operator()</code> of the function object passed to
+			the <classname>thread</classname> object's constructor.</para>
+
+			<para>A thread of execution  is said to be &quot;finished&quot; 
+			or to have &quot;finished execution&quot; when its initial function returns or 
+			is terminated. This includes completion of all thread cleanup 
+			handlers, and completion of the normal C++ function return behaviors,
+			such as destruction of automatic storage (stack) objects and releasing 
+			any associated implementation resources.</para>
+
+			<para>A thread object has an associated state which is either
+			&quot;joinable&quot; or &quot;non-joinable&quot;.</para>
+
+			<para>Except as described below, the policy used by an implementation
+			of &Boost.Threads; to schedule transitions between thread states is 
+			unspecified.</para>
+
+			<para><note>Just as the lifetime of a file may be different from the
+			lifetime of an <code>iostream</code> object which represents the file, the lifetime
+			of a thread of execution may be different from the 
+			<classname>thread</classname> object which represents the thread of 
+			execution. In particular, after a call to <code>join()</code>,
+			the thread of execution will no longer exist even though the 
+			<classname>thread</classname> object continues to exist until the 
+			end of its normal lifetime. The converse is also possible; if 
+			a <classname>thread</classname> object is destroyed without 
+			<code>join()</code> first having been called, the thread of execution 
+			continues until its initial function completes.</note></para>

-
-        <p>The <code>thread</code> class represents threads of execution, and
-        provides the functionality to create and manage threads within the <b>
-        Boost.Threads</b> library. See <a href="definitions.html">
-        Definitions</a> for a precise description of &quot;thread of
-        execution&quot;, and for definitions of threading related terms and of
-        thread states such as &quot;blocked&quot;.</p>
-
-        <p>A thread of execution has an initial function. For the program&#39;s
-        initial thread, the initial function is <code>main()</code>. For other
-        threads, the initial function is <code>operator()</code> of the
-        function object passed to the class <code>thread</code>
-        constructor.</p>
-
-        <p>A thread of execution is said to be &quot;finished&quot; or
-        &quot;finished execution&quot; when its initial function returns or is
-        terminated. This includes completion of all thread cleanup handlers,
-        and completion of the normal C++ function return behaviors, such as
-        destruction of automatic storage (stack) objects and releasing any
-        associated implementation resources.</p>
-
-        <p>A thread object has an associated state which is either
-        &quot;joinable&quot; or &quot;non-joinable&quot;.</p>
-
-        <p>Except as described below, the policy used by an implementation of
-        <b>Boost.Threads</b> to schedule transitions between thread states is
-        unspecified.</p>
-
-        <p><b>Note:</b> Just as the lifetime of a file may be different from
-        the lifetime of an iostream object which represents the file, the
-        lifetime of a thread of execution may be different from the <code>
-        thread</code> object which represents the thread of execution. In
-        particular, after a call to <code>join()</code>, the thread of
-        execution will no longer exist even though the <code>thread</code>
-        object continues to exist until the end of its normal lifetime. The
-        converse is also possible; if a <code>thread</code> object is destroyed
-        without <code>join()</code> having first been called, the thread of
-        execution continues until its initial function completes.</p>

-
-        <p>The <code>thread_specific_ptr</code> class defines an interface for
-        using thread specific storage. Thread specific storage is data
-        associated with individual threads and is often used to make operations
-        <a href="definitions.html#Thread-safe">thread-safe</a> that rely on
-        global data.</p>
-
-        <p>Template <code>thread_specific_ptr</code> stores a pointer to an
-        object obtained via <code>new</code> on a thread-by-thread basis and
-        calls delete on the contained pointer when the thread terminates. Each
-        thread initially stores the null pointer in each <code>
-        thread_specific_ptr</code> instance.</p>
-
-        <p>The template <code>thread_specific_ptr</code> is useful in the
-        following cases:</p>
-
-        <ul>
-            <li>An interface was original written assuming a single thread of
-            control and is being ported to a multi-threaded environment.</li>
-
-            <li>Each thread of control invokes sequences of methods that share
-            data that must be logically accessed through a globally visible
-            access point, but are physically unique for each thread, instead of
-            being explicitly passed.</li>

+//          Change "rd" to "read", "wr" to "write", "rw" to "read_write".
